MAX7219 Dot Led Matrix Module MCU LED Display Control Module Kit For arduino

MAX7219 is an integrated serial input / output common-cathode display drivers , which connects the microprocessor 7-segment digital LED display with 8 digits , bar graph can also be connected monitor or 64 separate LED. On type B BCD encoder includes an on-chip , multi-channel scanning loop , segment word drive, but also a 8x8 static RAM for storing each data . Only one external register is used to set the segment current for each LED .
   A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update does not overwrite all of the display . MAX7219 also allows the user to select each of the data code or not coded .
   The entire device includes a 150μA low-power shutdown mode , analog and digital brightness control , a scan-limit register allows the user to 1-8 bits of data , there is an LED light so that all the detection mode .
   Requires only three IO ports can drive a dot ! No flashing dot matrix display ! Support cascade !
Single module can drive a common cathode 8 * 8 dot matrix
   Module Operating voltage : 5V
   Module size : 5 cm X 3.2 cm wide X 1.5 cm high
   Holes with four screws , diameter 3mm, can be fixed by using our M3 studs
   Mdules with input and output interfaces , support for cascading multiple modules
   Is a block left input port, an output port on the right .
   When control of a single module , simply input port receiving CPU
   When cascading multiple modules 3 , output and input termination CPU, the input output termination module of the first two modules of the first one , the first two modules of terminating the input of the first three modules , and so on . ..
   To 51 single example:
   VCC → 5V
   GND → GND
   DIN → P22
   CS → P21
   CLK → P20
   1PCS MAX7219 dot matrix module ( finished with lattice , has tested well )
   5PCS DuPont line
